178 Chapter 16 Replacing the hard disk

3Place the hard disk assembly back into the BCM1000.

a Align the holes in the brackets with the holes in the bottom of the inside of the BCM1000. b Fasten the hard disk bracket to the housing.

4Reconnect the drive(s) to the system:

Note: All connectors have a notch that allow you to align the connectors correctly. If you cannot push a connector in easily, do not force it.

•Single hard disk: Connect the power supply to the hard disk connector, and the ribbon (IDE) cable from the controller to the hard disk.

•Mirrored hard disks:

a Reconnect the power cables as described below.

Warning: Ensure that you connect the hard disk cables to the same hard disk from which they were disconnected. Failure to do so may prevent the system from booting.

bConnect the Primary ribbon cable from the RAID board to the disk you removed it from.

If you are upgrading from a single-disk system to a mirrored system, this will be the disk on the bottom.

cConnect the Mirror ribbon cable from the RAID board to the disk you removed it from.

If you are upgrading from a single-disk system to a mirrored system, this will be the disk on top.

dEnsure that the third ribbon cable from the RAID board is connected to the IDE 1 connector on the controller (mother)board.
